Thanksgiving evening about 10 p.m. 9 objects were seen up in the sky making up different formations and changing from yellow to red. At one point two of the objects got side by side. The objects moved from left to right then would go straight and dissappear for a few seconds then come back down and reappear. All but 1 vanashed after about 15min. The last one flew slowly towards the west.
